Do you believe that he exploited the game while OP is not providing any evidences for the accusation against him? If you are a gambler and you are accused to do such thing but the casino do not provide any evidences and do not try to resolve it as fast as possible, what will you do? We need to use our logic to see the whole issue from both parties (not from one side only).
Well, dude I try my best to side on people who is more powerless when there's no evidence for both sides to present themselves as what they claim they are. Of course we need to use logic but it's difficult to judge when both are unclear right?
